Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain food by consuming other organisms.

Front

What gas is produced as a byproduct of photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons needed for the formation of glucose.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.
